Okay so.
I have bought a new pc (as of july this year) with the 14th gen intel (I know I know), and a 4070. And since the new expansion comes out, the game will not stop crashing.
I have had Illegal Instruction Errors, Radar Leaks, Memory Issues and a couple others all with the Legendary “press OK to terminate the program”
I am at a deadloss for what to do.
Its a brand new wow install, Windows 11 home is less than 2 months old, it crashes with and without addons, the pc is not overheating. I will post the DXDIAG event below (since I cannot seem to post the entire thing due to character limits
